There a fraudulent transaction showing in my account dated 27/5/2023 at 11:25:35 AM towards MC DONALDS VISHAKAPATNAM IN for Rs 31 . I contacted the SBI customer support and mailed to [protected]@sbicard.com but they were saying it' a paywave (contactless) transaction and it's a secure one and I am totally liable for it but the case was I didn't do it and at that time I was at home an my card is with me.
